  • a main problem to be solved by this invention is to make smooth movement of a float valve body on a lower side, that is, a lower float body for detecting an initial full-tank state, while making the dimension in the vertical direction as compact as possible, in this kind of valve device for fuel tank.
  • a valve device for fuel tank is a valve device to be installed and used on a fuel tank.
  • a case has an air flow valve orifice connected to outside of the tank at an upper part, and a fuel inflow part below the air flow valve orifice.
  • the case is divided into an upper chamber and a lower chamber by a partition formed between the air flow valve orifice and the inflow part.
  • An upper float body is disposed inside the upper chamber of the case and ascending by fuel flowing into the case to be seated in said air flow valve orifice.
  • a lower float body has an upwardly projecting guide shaft, supported inside the lower chamber of the case with the guide shaft being inserted to be movable vertically inside an insertion part formed on said partition, and ascends by fuel flowing into the case to close a main connect-through part between the lower chamber and the upper chamber formed on said partition.
  • a receiving hole for receiving the guide shaft of the lower float body is provided on said upper float body.
  • the fuel level inside the filler pipe is raised again by the pressure increase inside the tank, and a final full-tank state is detected by the sensor inside the fueling gun.
  • the fuel level drops, first the fuel flows out from the upper chamber, the upper float body descends, and the air flow valve orifice is opened. Next, when the fuel level drops further, the lower float body descends, and the main connect-through part is opened. Because the lower float body is supported with the guide shaft being passed through the insertion part provided on the partition, a gap is created between the side face of the lower float body and the inside face of the lower chamber and contact between the two can be prevented.
